介绍国内外钢结构制造线性控制的一般方法,对展览厅钢箱梁结构预拱模型采用ANSYS有限元软件进行受力分析,计算钢箱梁结构受到自重后的变形情况并拟合出多项式曲线,为结构预拱设计提供依据。
The general method of linear control of steel structure manufacturing at home and abroad is introduced. The prestressing model of the steel box girder structure in the exhibition hall is analyzed by ANSYS finite element software to calculate the deformation of the steel box girder structure under the condition of self - weight, and the polynomial curve is fitted. Provide the basis for the structure pre-arch design.
